The Schon DSGN Pocket Six Copper is made from copper and then polished to shiny perfection, as soon as you take it out, it will develop a patina. As each pen is colored by hand, the exact structure will vary on each pen.
The Pocket Six is a very small pocket pen, which needs to be posted to use. Because of the good treading, it posts very quick and then makes it a full size pen, with a number six size nib.
It uses standard international cartridges.
